Concurrent Signatures with Fully Negotiable Binding Control

Journal Article


Abstract


  • Since the introduction of concurrent signatures, the authorship

    binding of concurrent signatures has always been initiator-controlled,

    that is, only the initiator of a concurrent signature exchange can control

    “whether” and “when” to convert the exchanging ambiguous signatures

    to publicly verifiable ones concurrently. This binding control is not negotiable.

    In some applications however, this limitation is undesirable,

    and instead, as of optimistic fair exchange does, letting the responder

    control “whether” and “when” to have exchanged ambiguous signatures

    bound is needed. This motivates us towards constructing a new concurrent

    signature variant which supports negotiation between the original

    initiator-controlled binding and a new responder-controlled binding. In

    this paper, we formalize the notion and propose the first construction,

    which allows either the initiator or the responder to control “whether”

    and “when” the binding of the exchanging ambiguous signatures will

    take place concurrently. The scheme is backward compatible to the original

    concurrent signature and is also comparable in performance to the

    existing ones.
